Towards Green Wireless Networks: Energy-Aware Techniques for Emerging Applications with Evolving Network Architectures

过去十年见证了巨大的移动流量、无处不在的智能设备和各种新应用的爆炸式增长。虽然这种增长为全球移动行业带来了越来越多的收入，但人们对环境影响和高资本/运营支出的担忧也在增加。在经济和生态需求的双重驱动下，节能和绿色成为5G无线网络的主旋律之一。尽管这些需求已经引起了学术界和工业界的广泛关注和努力，但不断发展的网络架构需要不断增强绿色网络算法，以充分挖掘潜力。与此同时，新的用户驱动型应用不断涌现，需要有效的解决方案来保持可持续增长。

The past decade has witnessed an explosive growth of tremendous mobile traffic, pervasive smart devices, and assorted new applications. While this growth leads to increasing revenue for the global mobile industry, there are rising concerns on environmental impact and high capital/operating expenditure. Driven by the pressing needs from both economical and ecological perspectives, energy efficiency and greening becomes one of the dominant themes for 5G wireless networks. Although such demands have attracted considerable attentions and efforts from the academia and industry, the evolving network architectures need to be continuously augmented with green networking algorithms to fully harvest the potentials. Meanwhile, new user-driven applications keep emerging and call for efficient solutions to maintain sustainable growth.
